<p>PURPOSE: To enhance the power supply efficiency by reducing the magnetic reluctance of an air gap interposed at a route for passing a magnetic flux in the device for supplying the power without contact by electromagnetic induction of a moving body which moves on tracks. CONSTITUTION: A transmission line 3 for supplying a high-frequency current is disposed at a track, and a pickup unit 15 formed of a core member 16 made of magnetic substance with a substantially E-shaped sectional form and a pickup coil is provided at a moving body to supply the power without contact by electromagnetic induction. In such a structure, the central protrusion 16d of the member 16 protrudes larger than both side protrusions 16b, 16c. On the other hand, a pair of substantially L-shaped sectional magnetic members 21, 22 are laid on the tracks, and the main parts 21a, 22a and protruding parts 21b, 22b of the members are so disposed at both side of the ends of the protrusions 16b, 16c and the part 16d of the core member as to be opposed via infinitesimal intervals.</p> |
